From 0 to 1 Data Structures & Algorithms in Java - Introduction To Shortest Path In An Unweighted Graph - The Distance T

The video tutorial introduces shortest path algorithms, focusing on finding the shortest path between two vertices in a graph by traversing the fewest number of edges. It explains the problem statement, sets up a graph, and analyzes example paths to determine the shortest path. The concept of distance in graphs is discussed, followed by an introduction to the distance table and its relation to the BFS algorithm. The tutorial concludes with a detailed guide on filling the distance table using a specific path example.

What is the primary goal of a shortest path algorithm?

• To find the path with the fewest edges

• To find the path with the most vertices

• To find the path with the most edges

• To find the path with the highest cost

In the context of shortest path algorithms, what is a source vertex?

• A vertex with the highest degree

• A vertex from which the path begins

• A vertex with no outgoing edges

• A vertex with no incoming edges

How is the shortest path determined in a graph?

• By the number of vertices

• By the number of loops

• By the number of edges traversed

• By the total weight of the path

What does the distance in a graph represent?

• The number of edges in the path

• The number of loops in the path

• The number of vertices in the path

• The total weight of the path

What is the purpose of a distance table in shortest path algorithms?

• To track the number of loops

• To track the distance from the source to each vertex

• To track the total weight of the path

• To track the number of vertices

Which column in the distance table indicates the last vertex encountered in the path?

• Path column

• Last vertex column

• Distance column

• Vertex column

In an unweighted graph, what is the distance between adjacent vertices?

• Zero

• One

• Three

• Two

How is the distance of a vertex from the source calculated in the distance table?

• By subtracting one from the distance of the last vertex

• By adding one to the distance of the last vertex

• By adding the number of vertices

• By adding the number of edges

What is the distance of a vertex from itself in the distance table?

• Three

• Zero

• One

• Two

Why is it important to focus on a specific path when filling the distance table?

• To avoid confusion with other paths

• To maximize the number of edges

• To minimize the number of vertices

• To ensure the table is filled quickly
